<jats:title>Abstract</jats:title><jats:p><jats:bold>Background</jats:bold>: There are few guidelines for the appropriate mode of fluid administration during and after colic surgery, and is challenging to reach the right balance while avoiding overhydration. This study aimed to compare goal‐directed fluid therapy (GDFT) and ‘liberal’ fluid regimens (LFRs) in horses undergoing small intestinal surgery.</jats:p><jats:p><jats:bold>Methods</jats:bold>: Eighteen horses subjected to small intestinal surgery were matched according to the surgical lesion, type of anastomosis, length of resection, and duration of clinical signs. Horses in the LFR group were administered intravenous (IV) fluids for at least 24 h. In the GDFT group, IV fluids were administered only when considered necessary based on clinical parameters. Postoperative reflux (POR), packed cell volume, total protein, heart rate, venous lactate level, complications, and long‐term survival rates were compared.</jats:p><jats:p><jats:bold>Results</jats:bold>: Three horses in the LFR and one in the GDFT group developed POR. Horses in the GDFT group had a shorter time interval to first oral water intake and shorter hospitalisation time. Postoperative complication rates and survival were not different between groups.</jats:p><jats:p><jats:bold>Conclusion</jats:bold>: Further studies are necessary to set guidelines for the evaluation of hydration status and to plan postoperative fluid administration; however, GDFT may be a valid alternative to liberal fluid therapy after colic surgery.</jats:p>
